SPRAY MARKER.

Application filed August 25, 1924.. Serial No. 734,114.

This invention primarily relates to the marking of paper, fabric, and like materials; it involves methods and apparatus for marking as well as the product thereof ;and it includes novel features for dividing a mass of material into a plurality of groups or sections to facilitate their subsequent convenient handling.

Where material like paper, fabric, etc.,

is to be developed into a definite number of articles-like tens, dozens. scores, etc.-- it usually involves laborious counting and separating the elements of a mass. This is attended with expense, inaccuracies, trouble,

l5 inconvenience, etc.

In the manufacture and reeling of paper, for instance, a web is usually run from the paper-making machine onto a reel. When that reel has received its capacity, there is thereon a compact mass'of convolutes or layers. When out longitudinally and trans versely,there is a resultant pile of sheets of, perhaps, a definite number but undivided into hundreds, fifties, tens, etc., forsubsequent convenient handling, and then it is necessary to resort to the laborious counting of the same.

The object of the present invention is to provide a simple but effective method of marking the web periodically while being reeled, and this is accomplished by applying to the paper, etc., while in web-form and, preferably, as an incident to the same being reeled, a marking-substance-in the form of a liquid or other substance-which divides the same into sections or groups of a predetermined number of layers and which, when subsequently cut into sheets, are of a substantially definite and known number,

whereby the actual counting of the same is avoided.

Another object is to provide suitable apparatus, preferably associated with papermaking or papenreeling apparatus, or both, and. whereby a web of paper may be subjected to' application of, or impregnation with, a marking substance such as a fluid or the like at predetermined points so that, when reeled and subsequently cut into sheets, it will (in flatwise condition) constitute a pile definitely divided into a plurality of grou s or sections of sheets of substantially definite and known number.

My inventiveconcept involves a method,

apparatus. for practicing that method, and the product thereof.

The apparatus is susceptible of various embodiments; but I have (as the result of experimentation and practical development) determined that that which is herein disclosed has advantages which make it a desirable type to utilize. Primarily, it includes a paper-reel, means for supplying a web of paper thereto, and interposed mechanism for applying a marking substancein the form of a liquid-to the web as it is being wound on the reel. Such an apparatus is here revealed as operatively associated with a component of a paper-making machinein this instance a calenderand is illustrated in that connection in the accompanying drawings which are, however, merely illustrative, and wherein:

Figure 1 is a fragmentary view, in side elevation, of the apparatus constructed and arranged in accordance with the principles of my invention;

Figure 2 is a view, in sectional elevation, of the spraying-structure forming a component of the apparatus, the section being taken on the line 2-2, Fig. 3;

Figure 3 is a fragmentary view thereof;

Figure 4: is a view in side elevation of a modification, and includes automatic means for controlling the action of the marking structure Figures 5, 6 and vation, plan and section, respectively, of parts of the automatic structure; and

Figures 8 and 9 are views of apile and a roll of paper, respectively, being products of the method and apparatus and at different stages of production.

In these'drawings, the reference-character 1 designates a component of a paper-making machine, it being, in this instance, a calendermachine. Juxtaposed thereto is a reel 2 or similar web-recelving structure, supported on a stand 3. The machine 1 supplies a Web 4- of paper, fabric, or any other material, to the reel. The latter is operated or driven in any suitable w ayas by a crank 5 (or by drive-mechanism, not shown)t0 effect rotation of the reel and, thus, draw the web from the machine 1. In this manner, the web is wound uponthe reelreeledin a compact mass comprising numerous con volution s. In order that the convolutes may 7 are views in side ele- Jul horizontally disposed air-pipe 6, into which leads a supply-pipe 7 connected to a suitable source of air under pressure. In lieu of air, any other suitable pressure-fluid may be utilized.

Depending from the pipe are brackets 8, and these support an elongated reservoir or container 9, having a filling-opening at one extremity.

Associated with the air-pipe 6 and reservoir 9 are a series of atomizers or sprayers 10, 10. Each of these includes a nozzle 11, a short air-pipe 12 communicating with the pipe 6 and the nozzle 11, and a fluid-pipe 13 communicating with the reservoir 9 and the nozzle 11. It will be understood that, when air under more or less pressure is introduced into the pipe 6, it passes into the pipes 12 and out through the nozzles 11, at the same time drawing fiuidsuch as a colored fluid 14cfrom the reservoir 9 and effects more or less atomization thereof, at the nozzle, to produce a spray 15 and project the same against the outermost layer or convolute 16 on the reel 2 and which thereupon becomes more or less impregnated with the fluid. It is to be understood that the marking-substance contained in the reservoir 9 may be other than a fluid, such as a powder or other mass capable of adhering to the surface of the web and marking it.

The passage of the air into the pipe 6 is, in this instance, controlled by a valve 17, conveniently disposed so that, at required times, an attendant may normally operate it and turn on the air and effect a spraying of the web being wound on the reel. Usually, there is a counter (not here shown) on the reel to indicate the number of turns it has made so that it may thus be known how much paper has been wound on the reel. and which, according to general. practice, would be a predetermined amount.

It is also within the principles of my inventive-concept automatically to control the spraying operation; and. in Figs 4;, 5, 6 and 7, I have shown an automatic structure for that purpose: In this instance, the calendermachine 18 is of a somewhat different type; but it supports the pipe (3, reservoir 9, etc., for producing the spray 15 on paper being wound on the reel 2.

In lieu of the hand-operated valve 17, I employ (in this instance) an automaticallyaetuated valve 19. This would include a stem 20 on which a ratchet-wheel 21 is mounted. Coacting with this wheel is 2.

pawl 22 carried by an actuator 28, which is operated by a springcontrolled member 24L connected to an eccentric 25 carried by a ratchet-wheel. 20 and which is operated by a pawl 27 supported on an actuator 28. This, in turn, is operated by a connectingarm 29 carried eccentrically on a disk 30 fast on the shaft 31 of the reel 2. To vary the action of the structure just described, an adjusting device 32 is associated with the disk 30 and whereby the movement of the arm 29 and the parts operated thereby may be changed, as may be required. The ratchet-wheel 26 is held against retrograde rotation by a detent 38.

It will be understood that, by the completion of each revolution of the reel, the automatic-device is actuated to register one or another of the passages 34: to the parts 35.

)Vhen a predetermined quantity of paper has been wound on the reel, there will show, on the ends of the paper-mass or roll a series of spaced-apart colored sheets, as indicated at 36 (Fig. 8); thus, the mass will show a plurality of accurate markings which will be indicative of, say, sections or groups of say, ten, twenty, hundred, as the case may be.

Upon completion of the reeling operation, the paper may be unwound from the reel, and may be cut transversely or both transversely and longitudinally as it is unwound from the reel, as by any conventional cutting instrumentality (not shown) juxtaposed to the reel. The cutting may also be done manually by the operator, if desired. In this way, the convoluted mass will be reduced to fiatwise condition and comprise a pile 38 (Fig. 8) with spaced apart markin gs 38 denoting groups of sheets, each group comprising a definite and known number of sheets.

My invention is equally applicable to other types of webs than paper, and to strips as distinguished from webs,

lVhat I claim is:

1. In a method of dividing a web into equal sections, the step of spraying a marking fluid upon a moving web at intervals predetermined by the speed of travel of the web.

2. The method of dividing a web into groups each containing a predetermined number of sheets which includes the steps of periodically spraying a marking fluid upon a moving web, severing the marked web into sheets and stacking the sheets as cut from the web whereby the groups will be indicated by the marking fluid on certain of the sheets.

3. The herein described method, which consists in winding a web of paper, fabric, or the like and, while the same is in motion and in eonvolute condition, periodically projeeting a body of marking fluid thereon.

4. The herein described method, which consists in Winding a paper-web or the like into a plurality of convolutes, and periodically projecting a body of marking fluid upon a predetermined portion of a convolute.

5. The herein described method, which consists in winding a paper-web into a convoluted mass, and applying a marking fluid to predetermined sections of the mass to measure the same into predetermined thickness. 1

(3. The herein described method, which consists in reeling a web of paper or the like into a compact mass, periodically applying a marking fluid thereto to mark thickness-indications thereon, and cutting the mass into predetermined sheets with the fluid-markings thereon Visible to denote the approximate number thereof.

7. A method of treating paper which consists in supplying the same from a paper making machine, in web-form, winding the same into a mass of predetermined dimensions, periodically applying a marking substance to the mass during the winding operation so as to impregnate the Web at predetermined points with said substance and, thus, incorporate in the mass a series of divisions, and cutting the mass into sheets so that, when in piles, Visible markings appear at the edge to denote sections of a predetermined number of layers.

In testimony whereof I afiix my signature] WILLIAM H. CANNARD.
